As winter approaches, the process of replacing the roller bearings of biomass pellet machine is different from that in summer. Due to the drop in temperature in winter, there are many matters to be noted when replacing the roller bearings to ensure that the bearing life of the pellet machine does not decrease due to human operation. Today, Shandong TONY Machinery will explain to you the installation precautions for the roller bearings of biomass pellet machines in winter:

1. When disassembling the roller bearings of the pellet machine, it is necessary to ensure the cleanliness of the installation surface and the installation environment to prevent environmental dust from affecting the installation. In addition, it is necessary to check whether there are any foreign objects such as burrs, iron filings, or dust in the new bearings. Otherwise, the bearings may produce noise and vibration during operation, and even damage the raceway and rolling elements.

2. Before installation, the bearings must be cleaned. Because before leaving the factory, to protect the surface of the raceway and rolling elements from rust, anti-rust oil or anti-rust grease is injected between the raceway and the rolling elements. Therefore, it is necessary to clean with clean gasoline and kerosene, and then apply clean, high-quality or high-temperature lubricants before using. The cleanliness has a significant impact on the bearing life and vibration noise.

3. Choose the correct lubricating grease. Lubricating grease is made of base oil, thickener, and additives. Different types and different brands of the same type of lubricating grease have significant differences in performance, and the allowable rotation limit is different. The performance of the lubricating grease is determined by the base oil, and the thickener also affects the lubrication performance. The water resistance of the thickener determines the water resistance of the lubricating grease. Generally, low-viscosity base oil is suitable for low temperatures and high speeds; high-viscosity is suitable for high temperatures and high loads. Different brands of lubricating grease cannot be mixed. Moreover, even the same type of thickener lubricating grease may have adverse effects due to different additives.
